Purpose
Returns the base of the natural logarithm raised to the specified power. 
Parameters
x is an arithmetic expression. 
Examples
EXP(2.0)  /* returns approximately 7.389056 */
Restrictions
An EXP operation on floating-point decimal data is actually performed using the floating-point binary operation. Thus, the range of the operands and the result of the operation are limited to the ranges for floating-point binary numbers. 
 
Description
The EXP function returns the value of the base of the natural logarithm e raised to the power of x or e**x.
The result has the same data type as x.
